Box oovnn.

Application filedApril 25, 1927. Serial No. 186,451.

kinds of dry goods, are put up in containers by the manufacturers whichare suitable in which to leave the goods for display and inspection bycustomers in the stores, after the tops have been removed therefrom.Such display, however, must be made in accordance with the sanitary lawswhich have been passed in the various States,so that the edibles, ifthat be the kind of goods displayed, may be kept in pure and freshcondition.

'lransparent box covers heretofore used for such display of goods arenon-adjustable. It is a primary objcct'of the present invention toprovide an adjustable cover which can be used upon boxes of varyingsizes, which can be made cheaply and at the same time comply withtherequirements of the sanitary laws.

Further objects and advantages of the in vention will be set forth inthe detailed description which follows.

In the accompanying drawings:

Fig. 1 is a plan view of the cover in place upon a box.

Fig. 2 is a side elevation of the same.

Fig. is a vertical View in section illustrating the manner in which thesections of the cover overlap at the top and sides of the I box.

Fig. 4 is a perspective View of one of the outer sections, hereinafterdescribed, and

5 is a sectional view showing the means for holding the sections infixed relation to one another.

Like numerals designate corresponding parts in all of the figures of thedrawing.

In carryin out the invention, we provide a pair of frame sections 5,which are disposed at diagonally opposed corners of the box, and a pairof frame sections 6, which are disposed at the other corners of the box.

Each of the sections 5 comprises a right an box 4, and has a horizontalflange 7 extending inwardly along the edge of the box, and a verticalportion 7 b extending downwardly along the outside edge ofthe box.

A horizontal inner flange member 7? is affixed beneath the flange 7 andin spaced relation thereto, to provide a recess or groove for holding apane of glass, celluloid, or other transparent material 10, in positionover the top of the box. The frame sections -6 are disposed in suchposition as to slide beneath the frame sections5, when the cover isbeing adjusted upon the box, and have parts 9938, 8 which correspond tothe parts 7, 7", 7 of the sections 5; The lower edge of the verticalportion 7 is curvedupwardly and inwardly to form a way or trough 9 andthe lower edge of the member 8 is off-- set at 11 to fit in the troughQ-and to slide therein when adjustment of the cover is be-. 7

ing made. v

A horizontal rod 12 is fastened at one end 13 upon one of the lnnersections 6 and its free end extends through a projection 15 upon one ofthe sections 5, into a sheath or tube 14 attached to or formed in thever ticalportion 7 of the outer section 5. The

, 6 may be so adjusted with respect to each other that boxes of Widelyvarying sizes may be covered by the device, and that at all times thepanes of transparent material 10 are disposed in overlapping relation toeffectually prevent dust and dirt from getting into the box. Adjustmentmay be made in either longitudinal or lateral direction so that the samecover may be used upon a long or square box. Thus a box, which isslightly less in width than one of the panes of transparent material 10and which is only slightly less in length than the combined length ofone of each of the sections 5 and 6, may be covered, while square orrectangular boxes of various dimensions maybe covered.

lVhile it is preferred to use transparent material as stated, it ismanifest that the various adjustable sections may carry screen materialinstead of transparent panes, if desired, where the purpose sought is toprotectthe fruit from insects. It is manifest that many Ways may beresorted to for slidably mounting the sections with respect to eachother. However, the particular Way in Which the metal oi the frames'isbent to bring about sliding engagement between them is immaterial,because, as before stated, there are many Ways of accomplishing thisresult. Therefore it is to be understood that the invention is notlimited to the precise construction set forth pane and an L-shaped lramemember, sai

but that it includes within its purview Whatever changes fairly comeWithin either the terms or the spirit of the appended claims.

Having described our invention What We claim is:

1. The combination with a box having an open top side, of a coverthere'l'or, comprising tour horizontally disposed members, each of saidmembers consisting oi a transparent transparent pane being supportedWholly from its outer side and end portions by being gripped by itscompanion Lehaped frame member, the inner sidesand edges of saidtransparent pane being Wholly free to lie in snug and close fittingrelation to the other transparent panes, at such portions thereof asoverlap, two 0t said L-shaped frame members having their lower edgesbent to form V channeled portions adapted to slidably re ceive thecompanion L-shaped members, said frame members being of such Width as toextend down over and embrace the sides of the box to a considerableextent, to thereby insure the retention of the cover upon the ends ofthe transparent panes are received, a

two or said frame members being bent to channeled formation along theirlower edges to adapt them to shdably receive the vertical Webs oi' thetwo companion frame mem bers, and an offset rod'secured to one or saidtrams members, a perforate. element carried i by another oi said framemembers through Which-said rod slides, and a binding means carried bysaid perforate element.

8. A structure as recited in claim 1, in combination with a bindingmeans upon one o t said frame members anda rigid element upon.

another of said frame members slidably e gagged with said binding means,whereby when said binding means is tightened the frame members Will be;held: against slidi movement with respectto each other,

In testimony whereof they afiin their. signatures.
